flow water pipe must be routed to a suitable
drain and be inclined to prevent water pock-
ets, and must also be frost-proof. The over-
flow pipe must be at least the same size as
the safety valve. The overflow pipe must be
visible and its mouth must be open and not
located close to electrical components.
The safety valves must be actuated regularly

Maintenance
SAFETY VALVE (NOT ENCLOSED)
You can find the safety valve on the incoming pipe (cold
water) to VPB S/ VPBS S.
The water heater’s safety valve sometimes releases a
little water after hot water usage. This is because the
cold water, which enters the water heater to replace
the hot water, expands when heated causing the pres-
sure to rise and the safety valve to open.
The function of the safety valve must be checked regu-
larly. Perform checks as follows:
1. Open the valve.
2. Check that water is flowing through it.
3. Close the valve.
NOTE
If this pressurised water heater develops a
fault, e.g. a flow of hot water from the overflow
pipe, turn the heat pump off and contact your
installer.
NOTE
Do not remove or adjust any components that
are part of this pressurised water heater. Con-
tact your installer!
TIP
The safety valve is not delivered with
VPB S/ VPBS S. Contact your installer if you
are unsure how to check it.
